I'm trying to get 800x480 working using a PCI Radeon 9200 card and the 7" Lilliput.

I'm using a flexible PCI-riser (I had to extend the flex-cables) and cut a small part off the gfx board using a dremel (I actually cut off a piece of the VGA connector)to get it to fit inside my custom 1-din enclosure. I also had to cut of off about one centimeter of the stock Epia TC boards heatsink.

I have not yet managed to get the exact timings for the horizontal-pane (800 pixels) so the image still lookes a little "jaggy". But the vertical is ok.

800x480x70Hz or 800x480x75Hz seems to get me the best picture on my Lilliput using the Radeion, since 60Hz looks like crap.

Okie, here's my situation (and for others who use the same hardware setup)

I am using a VIA EPIA TC-10000. It has onboard video which is base on S3 chipset. It outputs standard resolutions, ie 640x480, 800x600, 1024x768 ect.....
note that these are 4:3 aspect ratio (ie horizontal:vertical)

if you are using this board on standard VGA display, all's danty and fine.

However, for those of us using 7inch touchscreen panel from Xenac/Gain/Lilliput, it spells trouble. If u have notice, those panels are wide format, and to make it worse, it's not the more common 16:9 format which some of u assumed it to be (848x480 = 16:9). It turns out that the panel has native resolution of 800X480 (5:3).

And this is not support by the onboard video.

Some might ask why not just leave it at 848x480? it's not that far apart? it's 16:9 compare to 15:9. the fact is, it does matter. Circles ain't circles, and text don't look right (coz it's not dot for dot).

The direct alternative is to use 1280x768 (5:3). In this case, the aspect ratio issue is resolved, BUT not the text. U can barely make out your text.

Hence the quest.

ps. if you think aspect ratio for PC monitors are confusing, wait till you work with video ON PC.
